Precision Motor Yacht Propulsion

A Performance and Quality-Oriented Approach to Production and Bespoke Motor Yachts

At CJR Propulsion, we bring a performance and quality-oriented approach to production and bespoke motor yachts, offering a complete design and engineering service for the supply of propellers and sterngear packages, specifically for vessels up to 30 metres, and for four or five blade propellers.

Whether you have a brand new motor yacht in build, or require a replacement solution, our fully optimised, CNC machined, Class S propellers and sterngear packages can be manufactured in as little as two weeks, using our rapid production process, and are used by leading boat builders around the world, including Sunseeker, Princess, Galeon and Ferretti.

With decades of experience, combined with the very latest in design and production technology, we know what it takes to design and manufacture the perfect propeller and sterngear package. We also understand how the design of your propellers and sterngear need to match your individual requirements. Because of this, we work with you to understand how your vessel is going to be used and design a solution to match, and always at a competitive price.

Not all propulsion systems are created equal

We don’t use standard off-the-shelf patterns, or a ‘hand-made’ close match approach, and we typically design and manufacture for a specific vessel. This provides our customers with peace-of-mind that everything we supply is going to perform exactly as expected, with maximum performance, efficiency, longevity and ride comfort.

Take a moment to explore our design and manufacturing process to understand the CJR difference and why we are confident our products are amongst the best in the world.
